NrrE TATES' IMPROVEMENT IN PLOW'S.

Specification forming To all whom it may concern:

Be it known that I, SAMUEL R. BLIVEN, of McDonough, in the county of Ghenango and State of New York, have invented a new and useful Improvement in Flows; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- 7 Figure l is a longitudinal vertical and central section of my improvement. Fig. 2 is a horizontal section of the same, taken in the line mm, Fig. 1.

Similar letters of reference indicate corresponding parts in the two figures.

This invention relates to an improvement in that class of plows which have certain parts so arranged that they may be reversed in position, so as to turn the sod from either side of the implement, as occasion may require.

This invention consists in the employment or use of two stationary mold-boards in connection with a reversible share, the above parts being constructed and arranged as hereinafter described.

To enable those skilled in the art to fully understand and construct my. invention, I will proceed to describe it.

A represents the back framing of the plow, and B Brepresent two mold-boards, the front parts of which are attached to a standard, 0, the upper end of which is attached to the beam D. The back parts of the mold-boards are attached to the lower parts of the framing The two mold-boards are precisely similar, except that they are curved in reverse form, one to turn the sod to the right and the other to the left of the plow. (See Fig. 2.)

E is the share, which is formed with three sides tapering to a point. One side, a, is the share proper, and the other two sides, b 1), form the sole or bottom of the same, either side being used as the sole, according to which side of the implementthe side a is to be adjusted. The share side, a, is somewhat wider than the other two sides, I) b, so as to allow a cuttingedge, c, to project as usual beyond the side or (See Fig. 2.) The share E is attached to the front end of a shaft, F. The front part of this shaft has its bearing in the standard 0, and its back part has its bearing in a cross-piece, d, of the framing A, and the back end of the shaft is secured part of Letters Patent No. 20,984, dated July 27, 1858.

in the lower end of a lever, G, which has its fulcrum at e. The shaft F is allowed to slide longitudinally in its bearings, and is allowed to turn, and the back end is fitted loosely in the lower end of lever G, so that it may turn therein; but the lever is allowed to move the shaft longitudinally. To effect this a pin, f, is inserted in the shaft at each side of the lever G. (See Fig.1.) To the back end of the shaft Fan arm, H, is attached, and in the inner end of the share E pins g are inserted, said pins fitting in holes in the front side of the standard and preventing the share from casually turning. The upper end of the lever G is fitted in a guide, h, and a lever, i, is fitted in said guide, the lever, when the share is adjusted, serving as a stop to lever G by confining the upper end of lever G in the front part of the guide It. (See Fig. 1.)

From the above description of parts it will be seen that by drawing back the upper end of lever G the shaft F will be shoved forward, and when the pins 9 are free from the standard O the share E may be turned either to the right or left, and made to coincide with either moldboard by actuating the arm H, the movement of which is controlled by pins h, attached one to each handle A. When the share is adjusted in either position it is retained by the pins g, and the lever G is secured by the lever or stopt'. The plow, therefore, may be made to turn the sod at either side, as occasion may" require.

1 do not claim broadly a reversible share, for they have been previously used, although I am not aware that they have been arranged like the one herein shown. I

I am also aware that double mold-boards have been used. I therefore do not claim such; but,

Having thus described my I claim as new, Patent, is

The reversible share E, attached to the shaft F and connected with the lever G or its equivalent, in combination with the two mold-boards B B, the parts being each other,

and desire to secure by Letters arranged relatively with as and for the purpose set forth.
